LIQUID-DISPENSING DEVICE.

Application ile` April 25, 1924. Serial No. 708,977.

To all whom t may concern.'

Be it known that I, DoUGLAss G. ToMnrNs, acitizen of the United States,residing at New York, in the county of Bronx and State of New York, haveinvented new and useful Improvements in Liquid-Dispensing Devices, ofwhich the following is a specification.

This invention relates to liquid-dispensing devices, particularly thoseof a character suitable for facilitating supply of controlled amounts oflubricating oils, etc. The invention will be understood from thefollowing description, taken in connection with the accompanyingdrawing, in which- Fig. 1 is a longitudinal sectional View of thedevice;

Fig. 2 is a bottom view; and

Figs. 3 and 4lare enlarged sectional details.

In the drawing the reference numeral 1 designates a container, which maybe made up of tin-plate or other suitable sheet material and which mayvary somewhat in 25 its precise form, but preferably will be of squareor rectangular cross section, as more convenient for handling. Thecontainer is provided with a nozzle or spout 2 having an inturned orinserted flange member 8 which is shaped to form a valve-seat 1 againstwhich may rest a valve 5 having a washer of leather, prepared liber orother desired material. The valve is carried on the end of the rod 6which preferably is- 35 compensating as to length, as by being providedwith curvatures 7 or other means to allow of a small amount oflongitudinal take-up for a purpose to be referred to more in detailhereinafter, and near the other end of the rod is a vent-valve 8 whichhas a sleeve extension 9 embracing the enlargement l() on the end of therod and thence projecting on as a tubular journal for the actuating bar11. The end of the sleeve is enlarged or headed up to retain theactuating` bar against disengagement. The ventvalvc 8, as in the case ofthe spout-valve 5, is provided with a suitable washer face, and coactswith a valve-seat l2 internally of the vent opening. Upon the bottom ofthe container is a cam-like surface or ridge 13 against which the innerface of the actuating bar 11 rides, and externally of the 5 bar 11- isan insert member 14 having a cam-ridge 15 generally parallel to thecamridge 13 for engaging the outer face of the bar. T ie bar 11 thusrides between the two cam surfaces.

With the actuating bar 11 swung around into the diametrally-spaceddepressions 16, the valve-rod 6 is carried forwardly. unseating thespoutvalve and the container in inverted position can be lilled on asuitablev charging device. Similarly, in use by inverting the containerand swinging the bar 11 around into the depressions 16 ,the oil or otherliquid can be discharged to the amount desired and the valve 5 then beclosed by swinging the bar 11 around in its campath until tight. It willbe noticed that while the spout valve 5 is open the vent valve 8 is alsounseated so as to allow passage of air to permit flow, but when thespout valve is drawn back against its seat the vent valve 8 is alsodrawn up against its seat and the container can be set upright or beplaced in any position without danger of leakage at either bottom orspout. The compensation curvatures 7 in the rod 6 allow of sufficienttake up either way to at all times insure the simultaneous seating ofboth valves.

I claim:

l. In a liquid-dispensing` device, the combination of a container havinga spout provided with an internal valve-seat and a bottom provided witha vent-opening, a valve seat internally of said vent-opening, a valvefor coacting with said spout valve-seat, a vent-valve for coacting withthe vent valveseat, a compensating valve-rod carrying said spout-valveand having an enlargement on its other end, a sleeve extending from saidvent-valve and embracing the enlargement on the end of the valve-rod,and projecting as a tubular journal, an actuating bar mounted on saidjournal, a cam-surface on the bottom of the container against which saidbar rides with its inner face, and an insert member presenting acam-ridge parallel to the first mentioned cam-surface for engaging theouter face of said actuating bar.

2. In a liquid-dispensing device, the combination of a container havinga spout provided with an internal valve-seat and a bottom provided witha vent-opening, a valveseat internally of said vent-opening a valve forcoacting with said spout valve-seat, a vent-valve for coactingl With thevent valveseat, a valve-rod arryiug said spout valve and having anenlargement on its other end, a sleeve extending from said Vent-valveand embracing the enlargement on the end of the valve-rod, andprojecting as a tubular journal, an actuating bar mounted on saidjournal, and parallel cam surfaces carried by the container bottombetween which said bar rides.

3. In a liquid-dispensing device, the combination of a container havinga spoutvalve and a bottom provided with a ventopening, a valve-seatinternally of Said ventopening, a valve-rod carrying said spout valveand having an enlargement on its other end, a Sleeve extending from saidventvalve and embracing the enlargement on the end ot the valve-rod andprojecting as a tubular journal, an actuating bar mounted on saidjournal, and a cam surface carried 20 a bottom vent-opening, a rodcarrying a 25 vent-valve Seating in the Ventbpemng and having anenlargement on its end near the vent-valve, a sleeve extending from saidvent-valve and embracing the enlargement on the end of the valve-rod andprojecting as a tubular journal, and an actuating bar mounted on saidjournal.
